However, rural communities have played an important role in society. They strengthened the traditional values ​​of the community, supported the ideals of individualism. Both community and regional development rely on inputs and interactions between various forms of capital, including financial, physical, environmental, human and social. In this context, capital is defined as a resource that is reinvested to create new resources (Flora et al., 1992:133). Each form of capital is important for its ability to benefit the productivity and efficiency of other forms of capital. For example, social capital encourages trusting and cooperative relationships that ultimately reduce transaction costs, thus making physical, human and financial capital more efficient (Burt. 1992; Flora and Flora, 1994; Smith, 2002) . But in most developing countries, economics and social analysts often observe countries with similar endowments of natural, human, and physical capital achieving different levels of economic success. Grootaert and Bastelaer (2002) confirmed the role of social capital in terms of generating a positive contribution to the economic and social well-being of the community. However, the concept of social capital from an economic perspective has not yet been demonstrated as part of rural and regional community development agenda in most developing countries. However, so far, there are insufficient studies that attempt to realize the impact of social capital on the development of rural and regional communities in Sri Lanka. The existing literature in the field does not provide adequate empirical evidence on the link between the development of social capital and the development of rural and regional communities in Sri Lanka. Therefore, it is time to analyze the impact of social capital development on the rural and regional community
